To att z /tom, may; concer/'tf tion, partly in section, Of the Be it ,known that I, Grenen l?. Lineair, a i `on the shaft, citizen of the United States, residing atChil section taken at line 8 3 of Fig. 2. f cago, in the county of Cook, State of Illinois, -filteferring to the drawings,4 in which corhave invented certain vnew and useful Imlresponding parts are indicated by like referprovements in Speed-ftegulating li'iechan- Llfence characters, 10 indicates a shaft which is ism, of which the following-isa specification, {Shoa/n as broken off at one end andv sup: reference being had to the accompanying ,ported at the other drawings. his held in a bearing-block 12 which. ma lbe l. ysupported, in any suitable manner. 13.1ndi- "eates a pulley journaled on said shaft, the

speed regulatirfr mechanism for shafts and similarly rotatii members, and its object is to provide a new and im roved means by which the rotating speed oI a driven member may he regulated. .Y More particularly, its object is to providev mechanism controlled by iid pressure by;` means of which the speed of rotation of a rotating member, when once it attains a given speed of rotation, may be automatically maintained at'and be prevented from eX- ceeding that predetermined speed, regardless of temporary excesses of speed-in the driving member or mechanism to provide fluid pressure controlled mechanism by means of which the mechanism may be readily and conveniently regulated to adjust it for any predetermined speed, and by means of which the speed of the driven member maybe varied at-pleasure to any speed up to the speed of the driving member, and may be automatically maintained at any such speed. To that end my invention consists broadly in a pulley or similar revolu'ble member which may be either a driving or` a driven pulley, a shaft upon which vsaid pulley isk loosely mounted, clutch members adapted to effect an engagement between said pulley and said shaft, a cylinder on said shaft, a piston slidinglymounted on said shaft in said cylinder and adapted to be operated by fluid pressure to cause the clutch members to effeet an engagement between said pulley and ,said shaft at any desired pressure, centrifugally operated members adapted to throw such clutch members out 'oi` engagement against the action of said fluid pressure when a predetermined s' eed of rotation is reached, and means by willich while the machine is running the degree of pressure of the said Huid operated piston upon such'clutch-members may be varied at will and adjusted for any' predetermined speed by means of applye ing various degrees of pressure upon a compressible chamber. i

In the drawings :fFigure 1 is'a side elevation of the machine. Fig. 2 is a side elevaina ter described. 4

14 indicates levers each provided at one .end with aclutoh-member 15 and at the other fend' with a weight 16, one' vJing pivoted at each end of a support 17 which is keyed or otherwise non-'rotatably secured upon shaft l10. Each of said levers 14 isfprovided with lan arm 18 which projects inward toward the shaft 1 1 f As s liown in Fig. 3, the shaft '10 is provided with afcentral opening 19, which turns at right angles and communicates with the interior of a cylinder tight i pon the shaft '10 and therewith. 21 indicates a iston slidingl mounted on said shaft 10 anr provided witfl packing-strips 22 between it and the cylinder 2O and between it and the shaft 10.

It will b e evident that when water, or other fluid, is forced into the piston 21 will be forced out of the cylinder against the arms 18 and will tend. to force said arms toward the support 17, thus moving the so as to rotate outward toward and against the inner` causes an engagement between shaft 10 and pulley 13, the strength of the engagement de pending upon the force of the Huid pressure 1n the cylinder, as will be readily understood. It is evident, moreover, that if the shaft 10 is rotated, or if the pulley 13 is rotated while such fluid pressure is being applied to the cyl# inder to cause engagement between the shaft and said pulley 13, the weights 1`6 will ha ve a tendency'by centrifugal forceto 'cause the clutch-members to be disengaged pulley 1 3, and the magnitude of this force will be vdependent upon the speed of rotation, as is well-known.
